AB  - This dataset is the permafrost distribution data of the Kamalan River Basin in the Tahe area on the east slope of the Greater Xing 'an Mountains. Combined with measured borehole and pit exploration data, driven by terrain factors, vegetation factors, meteorological factors, and soil and thermal condition factor data, the model is constructed using machine learning method (random forest). The Overall Accuracy is 0.89. The reliable accuracy allows this permafrost distribution data to be used as a calibration benchmark and historical reference for permafrost simulation in the Kamaran River Basin under the background of global warming. The data format is GeoTIFF, with a spatial resolution of approximately 30 m, and the projection is WGS_1984_Albers.
